The be quiet! Straight Power 11 modular power supply offers quiet operation without compromising on quality. Certified 80PLUS Platinum, it offers excellent energy efficiency. An ideal choice for quiet configurations, multi-GPU configurations, multimedia systems and systems for 3D photo/video applications.
Thanks to its fully modular management, the Straight Power 11 Platinum 's cables that serve no purpose in the system are left out. As a result, the system always looks very tidy. Due to the less cluttered layout of the system, the air flow is more fluid, which means less noise and heat inside the housing. In addition, installation is much easier.
The high-end SilentWings 3 fan delivers superior airflow with very little noise. Thanks to its unique and optimised blade design, durable dynamic fluid bearing system and 6-pole motor, this fan eliminates operating noise, with the added bonus of minimal energy consumption and a very long service life. In addition, the funnel-shaped fan opening allows for increased airflow resulting in higher cooling performance.
The be quiet! Straight Power 11 Platinum is 80+ Platinum certified, with a maximum efficiency of 93.7% to 94.1% depending on the model. The main advantages are low power consumption and better cooled, quieter operation.
The Straight Power 11 Platinum power supply operates wirelessly on the DC side inside the power supply unit. This results in improved cooling airflow and limited signal disruption due to the elimination of cables. This innovative design also results in longer component life.

An animated power supply, but before you can saturate the 850w, you're going to have to blow your budget on components and, above all, your electricity bill.
Ultra-quiet, high-performance power supply, I really recommend it for a MAO configuration. Ldlc is top notch for delivery tracking.
This Be Quiet! power supply meets all the criteria for a "Very good product" award!
The first important point is that it's quiet, and the second is that it's powerful and robust, which won me over!
It's good value for money and I'd recommend it for use in your home.
Quality power supply that's very quiet, no coil whine (no high-pitched noise).
The cables are good quality, the power supply is stable in terms of electrical voltage and doesn't heat up very much.
There's nothing to say, it's a quality product that I intend to keep for 8-10 years without any problem.
I wanted to have peace of mind knowing that this well-built power supply had all the connections I needed.
to power the RTX 4070 SUPER and i5 12600 KF
will allow me to power the next CPU / GPU upgrade without any worries.
I took this power supply for my config 5900x and 4070ti 32go of ram 2 nvme with the cable bequiet 12VHPWR and nothing has to say extremely quiet! even by drawing 560 watt on it.
It's silent and offers a certain certified breadth, as well as a full range of connections for the long term.
Good power supply, very efficient and quiet, nothing to say about the quality of manufacture and assembly, perfect.
Very happy with this purchase, the kit is well equipped and the power supply does its job very well with an appreciable silence :D
It's not human, because it does its job without the slightest noise. What's more, it's modular.
